Abstract: <PICT:0820442/III/1> <PICT:0820442/III/2> <PICT:0820442/III/3> In a method for producing an article coated with polytetrafluoroethylene the active surface of the material from which the article is made is attacked with an acidic solution and then without employing pressure, polytetrafluoroethylene is deposited from an aqueous solution or dispersion on the attacked surface.  Two blanks 1 of the required size each to produce an article, such as a cooking utensil, are mounted adjacent separated by a rubber ring 3 and the space between them is evacuated by applying external pressure or through a valve provided in the ring.  The blanks are submerged in a tank 7 containing an acidic solution.  For aluminium blanks the solution may comprise hydrofluoric acid and hydrochloric acid.  A number of pairs of blanks may be treated at the same time by suspending them from a rod 13 above a tank of acid as shown in Fig. 5.  A single blank may be treated by using a suspension having a suction grip 10. Each blank is then coated with a film of polytetrafluoroethylene by mounting the blank on a rotatable support 16 and depositing the polytetrafluoroethylene on the centre of the blank from a nozzle 18. Excess coating is recovered from a tank 15 surrounding the support. The coating is then baked preferably using a hot platen under pressure.  The process is repeated to obtain the required thickness of film.  The blank is then formed to the required shape of an article such as a frying pan 21.  Specification 815,756 is referred to.ALSO:In casting aluminium and like cooking utensils with polytetrafluoroethylene to prevent adhesion during cooking, the active surface of the material from which the article is made is attacked with an acidic solution and then without employing pressure, polytetrafluoroethylene is deposited from an aqueous solution or dispersion on the attacked surface.

Abstract: 368,235. Rotary valves. SCHWAB, G., 954, Townley Avenue, Townley-Elizabeth, New Jersey, U.S.A. Aug. 27, 1930, No. 25637. Convention date, Sept. 7, 1929. Void [Published under Sect. 91 of the Acts]. [Class 135.] In a furnace system comprising a number of chambers which can be interconnected in pairs by passages 41 .. 50, the valves which control the communication between the chambers consist of ported rotary cylinders 30 each having a transverse partition 30a at the midpoint of its length, the spaces above and below the partition being in communication with the upper and lower ends respectively of the associated chamber. Each of the valves associated with one half of the chambers has two ports connecting with one pair of the passages 41 .. 50, in the case of the chamber 4, for example, the passages 44, 49 ; while each valve of the remaining chambers has ten ports which become operative in pairs according to the position of the valve. In the position of the valves shown in Fig. 2 circulation of heattransferring gas will be, say, upwards through the chamber 4, along the passage 44, downwards through the connected chamber 7, and along the passage 49 back to the chamber 4, the circulation being assisted by blowers 60 rotated in the appropriate direction. Each valve is operated by a motor 56 and this is controlled partly by a clock-operated mechanism comprising a wiper arm 107, Fig. 9, moving in a clockwise direction over a series of arcuate contact strips A .. J, and partly by the movement of the valve itself through contact strips 93 .. 98, carried by a disc 99 on the valve shaft, which bridge a contact plate 92, and contacts 100 .. 105 connected to the strips A .. J. The timing of the valve movements is thus determined by the clockwork mechanism, and the degree of angular movement by contact strips 93 .. 98. In the position shown the circuit for the last operation of the valve was completed through the contacts 92, 93, 100, B, while the circuit for the next operation will be completed when the arm 107 engages the contact C. The arm 107 also moves over two series of contact strips 110 .. 117, and 120 .. 127 which are connected to provide a reversing control for the fan motor 62. A modified form of valve, Figs. 10 and 12 (not shown), which provides openings of double the angular extent as compared with the valve shown in Fig. 2, comprises two concentric rotating cylinders which are rotated in opposite directions.
